Progress 09/01/19 to 08/31/21
Outputs Target Audience:Experienced and beginning farmers and ranchers, women in agriculture, minorities in agriculture, veterans of foreign wars,agricultural professionals, grower organizations, and industry personnel will be taught cultivar characteristics, production methods and marketing strategies associated with winter canola. Changes/Problems:The year presented challenges with reaching clientele and stakeholders in our traditional face-to-face settings. Many field days and in-person meetings were cancelled because of the COVID-19 pandemic. Thus, the PIs had to share results through a number of different means including virtual meetings, social media, radio, and popular press. The on-farm monitoring of crop establishment practices was not carried out because of the interaction it would have required with the producers. Interpersonnal interactions were discouraged because of the uknowns of the pandemic. However, there was no major change in the overall plan of work, objectives, or goals of the proposal. What opportunities for training and professional development has the project provided?Presented a guest lecture on canola breeding and research to Agronomy 630, Principles of Crop Development. How have the results been disseminated to communities of interest?Information for clientele was made available through the K-State Department of Agronomy websites, virtual extension programming, extension publications, radio and television interviews, social media, and popular press. Other co-PIs used means within their university systems to deliver information to clientele. The PD virtually attended the Project Directors' meeting for the Supplemental and Alternative Crop Competitive Grants Program in Washington D.C. in March 2021. He reported on the accomplishments, products, and impacts of this project to the US Canola Association Board of Directors and other key stakeholders. The PD is also an active, participatory member of the Great Plains Canola Association (GPCA). Attending meetings of the GPCA allows for stakeholder feedback on the research and extension goals of this project. What do you plan to do during the next reporting period to accomplish the goals?

Impacts What was accomplished under these goals?
This project supported the development and promotion of new and current commercial cultivars that are adapted and grown in the Great Plains region and nationally. In the 2019/20 growing season, which coincided with the duration of this project, roughly 39,000 acres of winter canola were planted to cultivars with a genetic component from the K-State canola breeding program. These acres were primarily located in Kansas, Oklahoma, and Montana. The following is a summary of the program's cultivar activities during the project period and relevant to Objective 1. Two cultivars, 'CP320WRR', which is Roundup Ready® (RR) and 'Torrington', which possesses enhanced winter hardiness, were sold commercially for the second time in fall 2019. 'Surefire' winter canola was sold commercially for the second time in fall 2019. Two cultivars, Surefire and 'KSR4652' (CP320WRR), received Plant Variety Protection certificates. Winter canola cultivar 'KS4719' was increased in 2019 and accepted for release in summer 2020. KS4719 possesses exceptional winter hardiness and is less prone to lodging in saturated soils. In trials leading up to release, KS4719 averaged significantly greater lodging resistance than Surefire and it averaged 10% greater lodging resistance than Torrington. This trait is signficant because accessive rainfall in the spring has caused considerable harvest management issues with canola growers in the region. Results from a blackleg tolerance trial conducted in Oklahoma showed a trend toward reduced severity of infection among the newest released cultivars compared to older releases from the K-State breeding program. Results from the National Winter Canola Variety Trial (NWCVT) have a significant national impact, helping producers make informed variety selections for their farms and allowing seed distributors to evaluate potential areas of adaptability and new markets. During the project period, seven Great Plains sites were harvested with yields ranging from 1,278 lb/acre to 3,423 lb/acre. Yields were lower than normal as a result of a dry growing season, fluctuating spring temperatures, and saturated soils at harvest. Eight sites were not harvested because of poor stand establishment, losses from winter kill, spring freezes, and rabbit feeding. In years when weather greatly impacts trial results, decision making can be challenged by poor data quality. Producers are reminded annually to use more than one years' data to make variety selections. For Objective 2, input management studies looked at nitrogen managment considerations for winter canola on the Great Plains. At NMSU, applying 25% of nitrogen requirement (N) in the fall, 25% at green up in spring, and 25% at flowering (approximately 75% of the recommended total), and 50% fall and 50% greenup, improved overall productivity and nitrogen use efficiency compared to applying 100% in the fall. At OSU, applying 60 lb/a N over three dates (fall, green up, and flowering) did not differ from a two-way split application (fall-spring) of 90 lb/a (the targeted high rate). These results may indicate lower N rates could be used with supplemental split applications over the growing season. A trial at Manhattan, KS evaluated the application of crop inputs under low and high management schemes. Compared to the low input (zero inputs) check, the high input (all inputs) increased yield by 196%. On average, the high input treatments increased yield by 146% over the low input treatments. Removing spring nitrogen had the greatest negative impact on yield. Results indicate maintaining inputs is critical for high yields and careful consideration should be taken when removing more than one input. OSU also conducted a winter survival study examining the impact of management factors. At 3 (check seeding rate), 1, and 0.75 plants per ft2, yield did not differ when standard management practices were maintained. At 0.5 and 0.25 plants per ft2, yield decreased by 27% and 67%, respectively. These results show at a very low plant population, respectable yields can be attained if standard management practices are maintained. NMSU carried out a study evaluating two open-pollinated (OP) and two hybrid varieties planted at 25% to 125% of recommended populations (500,000 seeds/acre for OPs; 300,000 seeds/acre for hybrids). Mean biomass production decreased with decreasing plant population. Harvest index averaged 0.27 across seeding rates and varieties. Mean seed yield was stable over cultivars and populations. In general, reducing populations slightly benefited the OP cultivars, but the same treatment reduced yield in the hybrids. These results suggest that winter canola can buffer its yield over a wide range of populations. Pre-emergence herbicides exist for canola production; however, most require tillage to be incorporated. Therefore, other options are needed for production systems using minimum or no tillage. At OSU, acetochlor has shown promising results but environmental conditions play a role in efficacy of weed control. Similar results were observed for clomazone. When adequate precipitation falls, weed control is adequate and phytotoxicity is low. When too much or too little precipitation falls, plant damage increased significantly. Clethodim and quizalofop applications were made to winter canola and potential links between the applications and the increased risk for winter decline syndrome were observied at OSU. Mutliple greenhouse and growth chamber studies revealed only one instance where winter decline syndrome was observed, and that occurred on the control treatments. Therefore, no linkages have been noted between the herbicides and the disease. Double-crop systems in the Great Plains include winter and summer crops. Wheat is the primary winter crop; however, winter canola has shown a yield benefit to subsequent summer crops. Across environments in Oklahoma, grain sorghum and corn yields were not significantly different when grown behind winter canola or wheat. However, differences existed when looking at individual years and environoments. When hot and dry conditions were present, summer crop yields were significantly greater behind wheat because of greater potential for water savings. In years with consistent moisture, the increased nitrogen demand following wheat decreased summer crop yields compared to following winter canola. For Objective 3, the COVID-19 pandemic greatly disrupted our ability to provide the educational activities we had planned for in person and in the field. In addition, field sites were plagued by poor establishment in the fall, thus there would have been limited research to show across the key areas of production. As a result, information was disseminated through social media, popular press, electronic agronomy updates, and radio.

Outputs Target Audience:Experienced and beginning farmers and ranchers, women in agriculture, minorities in agriculture, veterans of foreign wars,agricultural professionals, grower organizations, and industry personnel will be taught cultivar characteristics, production methods and marketing strategies associated with winter canola. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?Students in Agronomy 860, Advanced Plant Breeding, were presented a guest lecture on winter canola variety development, from the initial cross to variety release, in January 2020. How have the results been disseminated to communities of interest?Information for clientele was made available through the K-State Department of Agronomy websites, extension programming, extension publications, radio and television interviews, social media, and popular press. Other co-PIs used means within their university systems to deliver information to clientele. The PD attended the Project Directors' meeting for the Supplemental and Alternative Crop Competitive Grants Program in Washington D.C. in March 2020. He reported on the accomplishments, products, and impacts of this project to the US Canola Association Board of Directors and other key stakeholders. The PD is also an active, participatory member of the Great Plains Canola Association (GPCA). Attending meetings of the GPCA allows for stakeholder feedback on the research and extension goals of this project. What do you plan to do during the next reporting period to accomplish the goals? Torrington winter canola will be marketed by Ohlde Seed Farms for the third year in Kansas, Oklahoma, and Texas. Surefire winter canola will be marketed by Spectrum Crop Development in the Pacific Northwest for the third year. CP320WRR will be sold for the third year in the SGP amd Montana by CROPLAN by WinField. KS4719 will be increased for certified seed and a small portion of certified seed will be sold for the first time in summer 2021. Test cross hybrids, developed by the breeding program, will be tested in field for the first time in 2020-2021. Adapted cytoplasmic male-sterile (CMS) winter canola parent lines will be advanced through backcrossing. Private CMS parent lines are being converted to the TruFlex Roundup Ready Technology through backcrossing. KSU-derived CMS parent lines are being converted to the TruFlex Roundup Ready Technology through backcrossing. A third-year study at NMSU will evaluate the responses of hybrid and OP cultivars to different seeding rates under limited irrigation. Data from a three-year irrigation project at NMSU will be used to create simulations for winter canola in DSSAT using the CropGro model. Input trials will evaluate multiple crop inputs simultaneously in winter canola cropping systems. Singular input studies investigate these factors independently. However, a singular approach can result in an under or overestimation of impact from management factors that contrasts the complexity of modern cropping systems. Seven individual crop management practices and production inputs will be tested. A study will observe and manipulate the production and utilitzation of photosynthetic assimiliates (source-sink) in winter canola. A study will evaluate plant growth regulator use in winter canola to limit fall growth. A study will look at winter wheat and canola as previous crops for double cropping of summer crops. A study will report on herbicide carryover from previous crops and the limitations on successful canola production. A greenhouse study will optimize canola P fertility application, management, and uptake in winter canola.
Impacts What was accomplished under these goals?
Technologies (e.g. systems, methods, cultivars) developed by this project are assigned Crop Research Technology Readiness Levels (TRL). A TRL describes the availability of information and/or technologies for potential commercial use. The TRL scale ranges from 1 (opportunity/idea identified) to 10 (sustained production capacity achieved). The following accomplishments were achieved under the goals and objectives of the project. TRL ratings are provided for technologies where relevant. 1. Two cultivars, CP320WRR, which is Roundup Ready® (RR) and Torrington, which possesses enhanced winter hardiness, were sold commercially for the second time in fall 2019 and the assigned TRL for each advanced from 7 to 8. Surefire winter canola was sold for the second time in fall 2019 and its TRL advanced from 6 to 7. Winter canola cultivar, KS4719, was increased in 2019 and accepted for release in summer 2020. The cultivar will be licensed to a third party and its TRL advanced from 5 to 6. Since 2010, ten cultivars have been licensed to seven companies with distribution networks in the southern Great Plains (SGP) and Pacific Northwest (PNW). The Kansas State University (K-State) canola breeding program is the only one developing RR cultivars for the SGP and PNW winter canola markets. Cultivars containing a genetic component from the K-State breeding program were planted on over 35,000 acres in 2019/20. Results from the National Winter Canola Variety Trial (NWCVT) have a significant national impact, helping producers make informed variety selections for their farms and allowing seed distributors to evaluate potential areas of adaptability and new markets. The NWCVT is coordinated by K-State and all PIs on this project grow one or more of these trials. Seven SGP sites were harvested with yields ranging from 1278 lb/acre to 3,423 lb/acre. Eight SGP locations were not harvested because of poor stand establishment, losses from winter kill, spring freezes, and rabbit feeding. The blackleg screening nursery near Stillwater, OK evaluated winter canola cultivars and hybrids response to blackleg throughout the growing season. Leaf spot appeared at low levels in January and Februrary, but levels were not sufficient to evaluate visually. However, blackleg cankers reached moderate levels on basal stems compared to previous years. Averaged over entries, cankers developed on over 70% of the stems sampled with an average disease severity rating of 2.5. The reference cultivars Eurol and Bristol were among the most susceptible entries. Plurax CL, MH 16JCO76, CWH317D, CWH249D, and MH 16JDO85 were among the most resistant entries with disease severity scores <2.0. Yields were variable and were not significantly (P=0.05) correlated to levels of blackleg. For the K-State breeding materials, cankers developed on over 80% of the stems sampled with an average disease severity rating of 3.0. Disease did not become severe on the reference cultivars Eurol and Bristol. KS4792, KS4734, KSR4869, and KSR4870S had the highest disease severity (>4) while KS4892, KS4806, KSR4865S, and Wichita has the lowest (<2). Yields were variable and were not correlated to levels of blackleg. 2. A trial at Manhattan, KS evaluated the application of crop inputs under low and high management schemes. Compared to the low input (zero inputs) check, the high input (all inputs) increased yield by 196%. On average, the high input treatments increased yield by 146% over the low input treatments. The highest yielding treatment was the high herbicide treatment (1943 lb/a), which was all inputs minus a fall applied herbicide. Generally, applying a herbicide is a recommended management practice. However, in this instance a herbicide application would have garnered minimal yield increase because of low weed pressure in the study area. The high input treatments from highest to lowest yield were: all inputs minus herbicide, all inputs minus growth regulator, all inputs (check), all inputs minus insecticide, all inputs minus fungicide, and all inputs minus spring nitrogen. Removing spring nitrogen had the greatest negative impact on yield. There was no significant difference in yield between the low input treatments. All low input treatment yields were significantly less than the high input check. The TRL for this project will remain at 4 as another year of data is needed to support these results. A winter survival dataset was compiled from the National Winter Canola Variety Trial from 2003 until 2018 (190 site-years) and auxiliary weather data over the last 40 years. A regression tree analysis indicated that environmental variables related to minimum temperature, fluctuating temperatures above and below 0°C, and windchill during the cold period (winter) were the main factors accounting for winter kill. A large area south of 35°N latitude in the US was identified as having greater potential for overwintering success, opening more opportunities for farmers to diversify their cropping systems. A peer-reviewed journal article was produced from this study. Potential impacts include better understanding of winter conditions that lead to winter kill in the crop. A winter canola population trial did not establish becasue of severe drought conditions, thus observations were discontinued at NMSU in the 2019/20 season. 3. The production year presented challenges with reaching clientele and stakeholders in our traditional face-to-face settings. Many field days and in-person meetings were cancelled because of the COVID-19 pandemic. Thus, the PIs had to share results through a number of new means including virtual meetings and online videos. Other steps taken included agronomy production updates, refereed papers, professional society meetings (virtual), radio and television interviews, and social media. Several peer-reviewed publications, many supported by NIFA, were either submitted or published during the reporting period. Numerous abstracts, supporting the work of the PIs, were presented at professional society meetings.
